Provide recent syncer response lengths as a watch channel (#2602) 
* Minimal recent sync lengths implementation

Also includes metrics and logging, to make diagnosing bugs easier.

* Add logging to check what happens when Zebra reaches the chain tip

* Add tests for recent sync lengths

- initially empty
- pruned to correct length
- newest entries go first

* Drop a redundant `/` from a Cargo.lock URL

This seems to be a nightly or beta Rust change,
but hopefully stable just accepts it.

* Use metrics histograms to avoid overwriting values

* Add detailed syncer monitoring dashboard

* Increase the recent sync length to 4

This length makes it easier to distinguish between temporary and
sustained errors/syncs.

Jack Grigg e51f33a4b9 Use interoperable names for common metrics 
These names match the equivalent metrics in zcashd, enabling common
metrics to be collected across both node types.
